This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor Designed specifically to work with the Adafruit BME280 Breakout * http://www.adafruit.com/products/2652 These sensors use I2C or SPI to communicate, up to 4 pins are required to interface Use of this library also requires [Adafruit_Sensor](https://github.com/adafruit/Adafruit_Sensor) to be installed on your local system. Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

Check that the Adafruit_BME280 folder contains Adafruit_BME280.cpp and Adafruit_BME280.h Place the Adafruit_BME280 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.
